Yes, the problem with the theory is that it could be precisely the other way around. The last time we had a big drop, it was followed by a sudden buying spree, which leads one to believe just one person was making back the vast majority of the BTC that had been sold out of fear. The opposite of distribution, more consolidation into the hands of a few.
If we were to see a sudden rise in prices now, because someone is out there trying to buy 30,000 BTC at rock bottom prices, will that be greater or lesser distribution of Bitcoin?
It is extraordinarily unlikely that one, or a few, people could manage to corner a large amount of Bitcoin at these prices without sparking thousands of others to return to buying. At this point in the game no one can surprise the Bitcoin markets in this way because we can all see the orders and only a few Bitcoins are sold at a time meaning as soon as the price starts to rise you will see a frenzy.
If this frenzy did happen, however, it would be natural as most corrections need to test upper and lower bounds before stabilizing.
